Why Won’t My Christmas Cactus Bloom? (and How to Revive It)

The winter season brings hope and cheer, with houseplants usually adding to the festive atmosphere. But what happens when your Christmas cactus refuses to bloom? Don’t worry! In this article, I will share five practical solutions to bring your poor Christmas cactus back to life. Let’s dive in!

Five Reasons Your Christmas Cactus Isn’t Blooming

1. It’s Too Warm

Believe it or not, Christmas cacti need a drop in temperature to trigger blooming. If your cactus is currently enjoying the warmth of a south-facing window, try moving it to a north-facing window or near a door. The cool air from the opening and closing of the door will signal the approaching winter. Avoid placing your cactus in draft-free areas like bathrooms or on top of the fridge, as this may hinder blooming.

2. You Gave It Too Much Love Over the Summer (aka Stop Overwatering!)

Contrary to popular belief, Christmas cacti thrive on neglect. While they do require water every week or two, they can survive with minimal watering during the summer. In fact, these plants need a short period of drought to encourage blooming in the winter. So, if you forget to water your cactus for a month, don’t panic! However, once fall arrives, resume regular watering. After the blooms fade, you can reduce watering again.

3. It Didn’t Need to be Re-Potted

Surprisingly, Christmas cacti prefer to be root-bound. So, avoid repotting until your plant is around 3-4 years old or its roots start peeking through the drainage hole. When repotting, choose a pot that is only slightly larger than the current one. Also, make sure to use high-quality potting soil specifically designed for succulents. It’s best to wait until the cactus has finished blooming or until early spring before attempting to repot it.

4. It’s Getting Too Much Light

To prepare for blooming, Christmas cacti require at least 12 hours of darkness starting in October. This can be difficult in southern locations or if artificial lights disrupt the required darkness. To solve this problem, consider moving your plant to a room that is not frequently used in the evenings. By providing the necessary darkness, you’ll encourage your Christmas cactus to bloom successfully.

5. It’s Not Actually a Christmas Cactus

Did you know that there are three distinct types of cacti resembling the Christmas cactus? There’s the Thanksgiving cactus, the Christmas cactus, and the Easter cactus. If you’ve tried all the tips in this article without success, it’s possible that you have a different cactus variety than you initially thought.

Why Is My Christmas Cactus Blooming at Odd Times?

It’s fascinating to note that some Christmas cacti bloom continuously from Thanksgiving to Easter. My Christmas cactus had blooms shortly after I bought it in 2018 and surprised me with four random blooms around Easter in April. In 2019, it had a primary bloom around Canadian Thanksgiving in mid-October, followed by a second full bloom in early December. I even suspect that it will continue blooming until Easter this year.

Different varieties of Christmas cacti may exhibit varying blooming patterns. For my houseplant, consistent blooms indicate contentment with its current location. It thrived in a west-facing windowsill, shielded by a neighboring house, receiving limited light. Occasional drafts from the nearby back door and cooler indoor temperatures seemed to suit it well. Similarly, when placed on a north-facing windowsill near the front door, it thrived just as happily.

A Word on Patience

If you’re eager to see your Christmas cactus in full bloom, remember that plants require time to adapt to their surroundings. Provide your cactus with the best possible conditions for success, such as low light and a cooler location. If you’re already following the advice in this article, there’s no need to worry. Just be patient, and your plant will reward you with its magnificent blooms.
